My issue is: That hashrate has no point in being there.
Wait - what? You're jealous that I'm mining namecoins for my users?

If people want merged mining they go where it is offered.
Or they just don't need to do anything because they know that will earn namecoins for mining on my pool.
Unofficial testing is just a convenient way of risk reduction (for you).
It is "unofficial" because there were silly problems before and I didn't finish GUI yet. Sorry, but it looks like you never developed something what must be together 24/7 up and on bleeding edge (which MM definitely is).
The thing was announced way in advance so there was plenty of time to test on testnet.
Haha, the best thing on this sentence is that I have prepared merged mining weeks ago. But it started crashing on production network. Yes, sometimes things are crazy.
Stealing may not be the right term, but we (the people mining at official merged pools) would get more nmc if it weren't for you, even if you pay out the earning to your miners.
I don't know what to say to this, except - sorry, world isn't fair. It's the same as I can say "damn, I might earn much more if deepbit never come".
